To address these issues, this paper proposes an adversarial domain adaptive network based on dynamic class prototype and graph convolution (DPGC) with two core strategies to improve the classification accuracy of cross-domain few-shot HSI classification. The first strategy, dynamic class prototype, optimizes the position distribution of class prototypes by adjusting the weights of real and pseudo-labels, thereby widening inter-class distances and compressing intra-class distances. The second strategy, graph-based domain adversarial strategy, extracts local and global domain features and forces the feature extractor to generate domain-independent features through adversarial training, mitigating performance degradation caused by domain distribution differences. Experiments show that DPGC achieves the best classification performance on three hyperspectral datasets and the code is publicly available at https:\/\/github.com\/tiwchui\/DPGC.<\/jats:p>","DOI":"10.3233\/faia250798","type":"book-chapter","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:42:34Z","timestamp":1761126154000},"source":"Crossref","is-referenced-by-count":1,"title":["DPGC: Adversarial Domain Adaptive Network Based on Dynamic Class Prototype and Graph Convolution for Few-Shot Hyperspectral Image Classification"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-3451-550X","authenticated-orcid":false,"given":"Xiangrong","family":"Yan","sequence":"first","affiliation":[{"name":"School of Artificial Intelligence, Xidian University, Xi\u2019an, 710071, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4373-3661","authenticated-orcid":false,"given":"Caihong","family":"Mu","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Xidian University, Xi\u2019an, 710071, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9993-0731","authenticated-orcid":false,"given":"Yi","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Xidian University, Xi\u2019an, 710071, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2025"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA250798","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:42:34Z","timestamp":1761126154000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA250798"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,21]]},"ISBN":["9781643686318"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia250798","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,21]]}}}
